1. Consider the linear system (where  and  are constants):

x + 3y + z =  2x + y + z = 1 2x + 3y + 4z = 3

Find conditions on  and/or  such that:

(a) The system has a unique solution.

(b) The system has no solution.

(c) The system has infinitely many solutions.

 

 

 

2. Solve the following system of equations by computing the inverse of the coefficient matrix

No credit will be given for solutions obtained by any other method.

2x  4 y = 3

– 3x + 6 y + 4z = 6

x + 2 y  2z = 0
